oldboy python 3.5 week 1

看着视频学了老男孩python并作笔记

首先来一个程序员的仪式

print("hello world")

#!/usr/bin/env python

# -*- coding:utf-8 -*-

-------------------------------------------

name = input("name:")
age = int(input("age:") ) #integer
job = input("job:")
salary  = input("salary:")

info = '''
-------- info of  %s  -----
name:%s
age:%d #使用%d就只能输入数字 否则报错
job:%s
salary:%s
''' % (name,name,age,job,salary)

#print(type(age)   , type(  str(age) ))------改变变量

info2 = '''
-------- info of {_name}  -----
name:{_name}
age:{_age}
job:{_job}
salary:{_salary}
'''.format(_name=name,
           _age=age,
           _job=job,
           _salary=salary)

info3 =  '''
-------- info of {0} -----
name:{0}
age:{1}
job:{2}
salary:{3}
'''.format(name,age,job,salary)
print(info, info2, info3)

------------------------------------------

此时都是明文输入 如果需要密文输入时 可用如下代码
------------------------------------------

import getpass

_username = 'shing'
_password = 'abc123'
username = input("username:")
#password = getpass.getpass("password:")
password = input("password:")
if _username == username and _password == password:
    print("welcome user {name} login...".format(name=username))
else:
    print("invalid username or password!")
